You're actually remapping keyboard shortcuts in the operating system. (Is there a program in Windows that *doesn't* use ctrl-o for "File > Open"?) Please don't do that. It messes with users who primarily interact with the browser--and I'm not talking just about "power users" or whoever: You're messing with users who rely on screenreaders and those who for whatever reason don't use the mouse to navigate the UI, among others. Let me reiterate: Don't do this. Ever. There are other ways to use the keyboard to add functionality that don't at the same time violate basic principles of accessibility. But since those don't actually involve CSS for technical information, you'll probably want to consult HTML and JavaScript groups instead.
